IMPROVEMENT IN SUGAR-MILLS.

Specification forming part of Letters Patent No. 23,753, dated April 26, 1859.

Z' 0 all whom it nwy'concern:

Be it known that we, JOHN L. BROWN and ALVIN C. GREENLEAF, both ofthe city of Indianapolis, in the county of Marion and State I of Indiana, have invented a new andv useful Improvement in Sugar-Mills, of which the following is a full and exact description, refer- A is the frame; B, a lever attached to the` beveled wheel C, which gears with the wheel l), which is upon the saine shaft with and operates the roller E and spur-wheel F, which gears with the wheel G, which operates the roller I,which is upon the same shaft. J and J are suspended bearings or beams, upon which l[he journals of the crushing-roller I rest.

K and K are rods, which support the bearers or beams J J. The levers L and L vhave eccentric bearings, and are designed to givea uniform pressure or crushing force to the roller I, as will be shown. The weights M M are designed to regulate the force of thelevers L L. The rods N N pass down from the top of the frame (to which they are attached) through the beams or bearers J J, and `support the fulcrums of the levers LL. The setscrews O O are designed to adjust the bearers or beams J J, thereby varying the axis of the roller I. rIhe chute or hopper I), as the cane is passed through the same, small end or top first, strips oli" the leaves. Ve sometimes cover these openin gs with an elastic or variable slide, which rises or falls, adapting itself to the size of the stalk.

Q is a scraper and discharge-apron, upon which the crushed cane is passed out of the inill. R and B are conductors designed to convey the juice into the trough S.

rIhe following is the operation ot the mill.: The cane, being fed into lthe same through the hopper P, passes between the rollers E and I, the machine being operated by'thelever B, as shown. The roller l is adjusted by either tightening the rods K K N N or operating the set-screws O O. The eccentric-levers LLare so constructed as to retain about the same distance between the bearings and the fulcrums of the same, when their angles are varied,thus

equalizing their pressure or giving uniformity to the pressure produced bythe weightsMM.

By adjusting the weights M M, the required amount of pressure may be applied to the crushing-roller I. The effect of the eccentriclevers differs from that of the simple spring, in that while the force of the spring is varied according to the distance or extent of its operation, the levers may vary the force without destroying the uniformity of the pressure or force applied by them.

By operating the set-screws O O, the roller I may be adjusted to the roller E, although the ends of the same may be of unequal size.

rIhis is done by varying the axis of the roller I, as has been shown. This arrangement avoids theneeessity of turning the rollers perfectly true.

What we claim, and desire to secure by Letters Patent, is- I The combination and arrangement of the rods K K N N, levers L L, and bearings J J with the set-screws O O, when constructed and operated substantially as and for the purposes set forth. 1
